Probiotics and Fertility: Support Your Reproductive Health

You may already know this: fertility is sometimes a complex challenge… Influenced by far more factors than we imagine. Among them, the microbiota plays a (very) important role. Did you know that probiotics can rebalance this precious ecosystem and boost your chances of conceiving? So, whether you are a future mom or a future dad… Make yourself a coffee, get comfortable on the couch, and dive into this article! We'll tell you why these “good” bacteria are so important for your reproductive health.

Probiotics: what are we talking about?

Probiotics are living microorganisms naturally present in the human body. Often called “good bacteria,” they play an essential role in the proper functioning of our body. There is not just one type of probiotic, but several, whether they are in the form of bacteria (bifidobacteria, lactobacilli, lactococci…) or yeasts (saccharomycetes).

Where can we find them? Well, in foods rich in probiotics! Like:

• kefir;
• sauerkraut;
• Greek yogurt.

Or you can also take them in the form of food supplements.

Why consume them? Because these little bacteria help improve the composition of our intestinal flora (also called “gut microbiota”). But that’s not all! They also work hard to maintain the balance of our vaginal flora (this is referred to as the “vaginal microbiota”). For example, by working wonders to help fight against urinary tract infections. Thus, be aware that the quality of your microbiota proves very important for your health:

• digestive;
• immune;
• metabolic;
• and neurological.

In short, probiotics are excellent allies for health… And also for fertility!

Why are probiotics good for fertility?

For female fertility

Yes, did you know that the balance of your vaginal microbiota plays an important role in your fertility? A healthy vaginal flora, predominantly composed of bacteria of the genus Lactobacillus, is essential for maintaining an environment that protects against infections and imbalances. These “good bacteria” produce lactic acid, which keeps the vaginal pH low. And thus prevents pathogens from taking hold.

However, this balance can be disrupted by several environmental factors, such as:

• oxidative stress;
• antibiotic treatment;
• an unbalanced diet.

This imbalance, called vaginal dysbiosis, can contribute to recurring infections (vaginal infections, urinary tract infections...) and, indirectly, to a decrease in the chances of conception. For example, studies have shown that dysbiosis of the intimate flora and/or intestinal flora can reduce the rate of embryo implantation or increase the risks of early complications like failed pregnancies (or miscarriages), although these links still require further research.

The benefits of probiotics are numerous! They can, among other things, help the body restore this balance. And repopulate the vaginal microbiota with the right probiotic strains such as:

• Lactobacillus crispatus;
• Lactobacillus rhamnosus;
• Lactobacillus gasseri;
• or Lactobacillus acidophilus.

Some very scientific names to designate these bacteria that:

• support the strengthening of local immunity in your vaginal flora;
• help limit inflammation in your vaginal microbiota;
• help limit the risk of developing chronic infections;
• promote the prevention of urinary tract infections;
• and thus help reduce the risks of infertility.

For male fertility

Gentlemen, probiotics are not just reserved for women's health! Their role in male fertility is just as interesting. Because, as with us, sperm quality is often linked to factors such as:

• oxidative stress;
• various infections;
• or imbalances in the gut microbiota.

However, these factors could:

• damage sperm DNA;
• reduce their motility;
• and therefore their chances of fertilizing an egg.

A probiotic based on Lactobacillus reuteri, for example, plays an important role in regulating this oxidative stress. It acts as a natural antioxidant, and thus protects reproductive cells from damage caused by free radicals.

Let us also note that a balanced intestinal flora can indirectly support optimal testosterone production, a key hormone for sperm quality.

In short, a probiotic course can become an important asset for boosting reproductive health for both women… and men!

What can degrade your vaginal flora?

Your vaginal flora (just like your intestinal flora) is a fragile and complex ecosystem. Thus, several daily factors can disrupt this balance. And promote the development of bad bacteria or fungi. Here are the main causes to watch out for:

1. Antibiotics

Of course, antibiotics are essential in certain situations. That being said, they cannot distinguish between “good” and bad bacteria. Except that by eliminating the entire family of Lactobacillus, which you need for a healthy intimate flora… They can promote cystitis / urinary tract infections of all kinds, which are not very pleasant.

2. Hormonal disruptions

As always, hormones play tricks on us! And those linked to the menstrual cycle, pregnancy, or menopause can affect the vaginal pH. For example, a drop in estrogen can reduce the production of glycogen, an important nutrient for Lactobacillus.

3. Stress

Chronic stress can have repercussions on your vaginal flora. By disrupting local immunity and increasing cortisol production, it can unbalance the microbiota and make your vagina more vulnerable to infections.

4. An unbalanced diet

What you eat has a direct impact on your microbiota. However, a diet low in fiber and high in sugars could promote yeasts like Candida albicans, responsible for yeast infections. Prioritize foods rich in prebiotics and probiotics instead, which will take care of your intimate flora.

5. Unsuitable hygiene practices

The use of harsh soaps, vaginal douches, or even synthetic underwear can also unbalance your flora. These habits modify the vaginal pH and disrupt the bacteria meant to protect you. Increasing the risk of urinary tract infections that we would all rather avoid!

How to choose probiotics to support your fertility?

Today, more and more types of probiotics are popping up on the market. It’s hard to choose the right ones! How do you know which ones remain the most suitable for supporting your fertility? Here are some tips to guide you:

1. Prioritize a suitable probiotic strain

Because yes, not all probiotic strains provide the same benefits. If you are looking to boost your fertility, turn more toward bacteria of the Lactobacillus genus, such as:

• Lactobacillus crispatus;
• or Lactobacillus rhamnosus.

These bacterial strains prove particularly effective in helping to maintain a good pH and thus protect against infections and strengthen the vaginal microbiota. A combo that brings together probiotics for the intimate and intestinal flora will therefore be perfectly adapted to your needs.

2. Verify product quality

Not all supplements are equal. So, if you want to do a probiotic course, turn instead toward brands that are transparent about their manufacturing process. Make sure especially that their probiotics are formulated to withstand stomach acidity and arrive alive in the gut and vagina. This is why products in the form of gastro-resistant capsules often remain the most effective. Furthermore, it is essential that the cold chain is respected at every stage, from manufacturing to delivery, to preserve the viability of the probiotic strains, which are sensitive to heat. At Boome, this requirement is strictly followed, which is an approach that is rarely put in place.

3. Choose your own approach!

We frequently repeat this in our articles: every individual is unique. So… You are too! The same goes for your needs, which can vary according to:

• your age;
• your lifestyle;
• your medical history.

4. Combine probiotics with a healthy diet

Doing a probiotic course is good. But doing a probiotic course integrated into a healthy diet… It is (a hundred times) better! Yes, these bacteria work better in addition to a good, well-balanced plate, rich in fiber, and low in refined sugars and processed foods.

In short, probiotics naturally support your fertility by balancing your gut and vaginal microbiota and helping to create favorable conditions for conception. However, be sure to choose them carefully! And don't hesitate to speak with a healthcare professional. Because with the right approach, these "good" bacteria can become a real asset in your journey to parenthood!
